To all lwhom it may concern.'

Be it known that I, MICHAEL J. POWER, residing at Nekoosa, inthe county of Wood and State of lVisconsin, have invented cer-V tain new and useful Improvements in Wrapspecification.

My invention relates to lwrapping machines, particularly to machines adapted for wrapping paper rolls before shipment from paper mills.

Paper rolls in paper mills are usually wrappedy before shipment by winding paperaround the end sections of the rolls, then folding in the over-hanging ends of'the wrappings, andl then applying headers to the folded ends to hold these wrappings or caps in place. Heretofore the greater part of such wrapping has been done by hand, which, of course, is a very costly procedure, and the broad object of my invention is to provide a machine which will automatically wrap the paper rolls and deliver them ready for shipment.

More in detail, the objects of the invention are to provide a machine into which the rolls vare received from the mill and paper lengths automatically wound about the ends and then automatically folded in, and then caps automatically pasted over the folded-in ends; to provide improved mechanism for automatically feeding in the wrapping paper and cutting it into proper lengths; to provide improved means for applying pastlng material to the wrapping lengths; to provide improved means for automatically folding in and together the over-hanging ends of the wrapping lengths; to provide improved means for simultaneously cutting paper heads from automatically fed supply paper andfor pasting these heads against the folded-in sections of the wrapping caps; and to provide improved means for discharging the wrapped rolls from the machine; and in general to provide an all-around efficient machine and one of simple construct-ion for quickly and rapidly and entirely automatically wrapping paper rolls.

My invention will be clearly understood by reference to the accompanying drawingsJ in which- Figure 1 is a plan view; Fig. 2 is a side view looking from the left of Fig. 1; Fig. 3 is a side view looking from the right of Fig.'

5 is a more or less diagrammatic'view from the rightl of Fig. 1 with parts removed to show.more clearly the operation of more internal parts; Fig. 6 is a plan view with parts removed and parts of the heading mechanism shown in section; Fig. 7 is a front elevational view with parts removed and parts of the heading mechanism shown 1n section; Fig. 8 is a detached view showing cam arrangementcontrolling certain detent mechanism; Fig. 9 is a View taken substantially on plane 9 9, Fig. 6, showing cam mechanism for controlling the cutting blade; and Fig. 10 is a view taken substantially from plane 10-10, Fig. 6, showing cam mechanism for controlling paste applying apparatus.

The various operating parts of the machine are mounted on supporting framework designated in general A. Above this frame-work is a run-wayor chute 10 along which the paper rolls 9^ to be wrapped are fed to the machine. Extending transversely across the supporting frame of the machine is a shaft 11 journaled in the standards 12 and 13 carrying at its outer enda belt wheel 14 (see Fig. 1).` Between the stand ards the shaft also carries two conveyer plates 15 each formed by cutting semi-circular portions out of a circular disk to leave conveyer wings 15a and pockets 15". As shown, three such wings and pockets are provided for each plate. Directly below the shaft- 11 are the carrier rolls 16 and 17 mounted on shafts 18 and 19 respectively suitably journaled on the supporting frame Patenten May 14, 1912.

A of the bases of the standards 12 and 13 sprocket wheel 21 about which engages a chain 22 which passes also about a sprocket wheel 23 on shaft 18. Shaft 18 carries at its ends the belt wheels 24 and 25 respectively, belts 26 and 27 connecting these belt wheels with belt pinions 28 and 29 on shafts 30 and 31 respectively journaled in bearing boxes 32 and 33 mounted respectively on the sides of standards 12 and 13, as best shown in Figs. 2 and 3. At, the inner ends of shafts 30 and 31 respectively are mounted hubs 34 and 35 carrying the star-shaped folding members 36 and 37 respectively, the arms of these star wheels being of substantially semi-spherical form, as shown. The shaft 1l at its right end (Fig. 3) carries a 13 and having the end of its other arm pivoted to a cam rod `46 having at its rear end the head 47 provided with a longitudinal slot 48, this slot receiving the end of the shaft 49' extending transversely across the machine below the-bed plate a and suitably journaled at` opposite sides from said bed plate. The cam rod head 47 also pivots a cam roller 50 at one end of the slot adapted \to be engaged by the cam tooth 51 extending from hub 52 ,secured to the outer end of the shaft 49. With this arrangement, as the shaft 49 rotates, the tooth 51 and roller 50 will coperate once during each-revolution to i carry the cam rod 46 rearwardly to cause rotation of the bell crank lever 44, and withdrawal of the end of detent pin 42 from one of the.notches 39 of detent wheel 38, and immediately after the tooth 51 has passed the roller the parts will be free to allow the-spring 42 to press the detent pin against the detent wheel ready to enter the next notch 39 to again lock the shaft 11 and the conveyer members 15 against -rotatiorn each angular advance of the members 15 resulting in the conveying of a paper roll from the chute' 10 into position on the rollers 16 and 17.

The machine is intended to wrap paper lengths about the ends of the rolls', and accordingly, paper feed mechanism is pro vided for supplying paper lengths toeach end of the roll when in place on the rollers 16 and 17. At the rear end of each side of the machine there are standards 53 and 53, these standards forming bearings for a shaft 54 for accommodating the wrapping paper supply rolls 55, 55', one for each end of the rolls wrapped. In front of the standards 53 and 53'- thebed plate a -supports standards 56 and 56 at opposite sides, and in front of these standards are similar standards 57 and 57'. At the lower ends of the standards 56 and 56 a shaft-58 is journaled mounting the feed rollers 59 and 59 at opposite sides, and above these rollers are the top rollers 60 and 60 on shaft 61 also journaled in these standards 56 and 56. In the standards 57 and 57 are journaled theupper and lower shafts 62 and'63 bearing the lowerand upper rollers 64, 64 and 65, 65

respectively. Between the 53 and 56, 56 the bed blocks 66 and 66 ing the shaft 67 standards 53, plate carries bearing at opposite sides journalcarrying the guide rollers 68 and 68 respectively at opposite sides. The paper. from the roll 55 passes downwardly below the roller and then between the rollers 64 and 65, while the paper from the opposite roll 55 passes similarly through the rollers at that side of the machine. )n the right end of shafts 58 and 62 are mounted sprocket wheels 69 and 7() respectively with which an endlessk driving chain 71 meshes. This chain also passes over a guide. sprocket wheel 72 suitably pivoted on the bearing standard 57, as best shown in Fig. 3. The chain also passes over a sprocket wheel v73 atthe end of a shaft 74 journaled at its ends in extensions 75 and 75 on bearing standards 56 and 56', these shafts carrying paste applying rollers 76 and 76 which engage respectively with the upper feed rolls 60 and 60. The paste wheels dip into a suitable paste 68 then between the rollers 59 and 60,

containing pan 77 and carry paste to thel rollers 60 and 61 which apply it to the paper coming from the supply rolls 55 and 55. The shaft 58 also carries a pi'nion 78 meshing with a gear 79 mounted in a suitable bearing on the bed plate A, this gear wheel being intermittently rotated by thev gear wheel 80 mounted on the shaft 49, as best shown in Fig. 3, this gear lwheel having teeth over only substantially one-half its periphery. During rotation of the gear wheel 79 by the wheel 8O the` lchain 71 will be advanced and the various' members con? nected therewith rotated tocause predetermined lengths of wrapping paper to be fed forwardly to be used -for wrapping about lthe ends of the rolls on 'the rollers 16 and 17.

`Between the paper feed mechanism and the rolls 16 and 17 knife mechanism is interposed for cutting oil' the lengths of wrapping paper. This knife mechanism is `mounted on a beam 81 ,extending transversely across the bed plate A and carrying at its opposite ends upright bars 82, 83 and 82, 83 respectively (Figs. 2 and 3). Linksv 84 and 84 hang from pins 85 and 85 between the respective uprights, and the lowerends of these links suspend the knife bar 86. Thisknife b ar has a laterallyv eX- tending arm 87 to which is pivoted the upper end of a depending link 88 p'ivoted at its lower end to the arm 89 secured to the transverse shaft 90,journa.led in the bearing block 91 depending from the bed plate A. (See Figs.' 3 and 6). The inner end of this shaft carries an arm 92 at an angle with the arm 89 and pivoted at its end to a cam rod 93. As best shown'in Fig. 9, the rear end 94 of the cam rod 93 is longitudinally slotted and 'receives the hub 95 mounted on shaft 49. This hub has a flange 96 having a cam grooi-*e 97 ineits side., and on cam arm 93 is pivoted a cam roller 98 for engaging in this groove. In Athe position best Lesen-ae movement of rod 98 and downward movement of the knife bar to sever the Wrapping paper bands fed from rolls 55 and 55. There are also provided at each side of the machine in advance of the rolls 16 and 17 paste receptacles 99 and 99 for applying paste to the .trailing ends of the wrapping paper sections so that when the ends of these sections are finally folded over the ends will be pasted and prevented from unvvrapping. For each paste receptacle valve mechanism 100 is kprovided which, when raised, will cause paste to flow onto the paper. Each valve mechanism connects by means of a rod 101 with a bell crank lever 102, from which extends a cam rod 103 having a slotted rear end 104. This slotted end engagesa hub 105 on shaft 49, and each hub carries a cam iange having a cam tooth 106 for coperation with a caln roller 107 on the cam rod 108.

The mechanism thus far described is instrumental in applying the Wrapping ends to the rolls, and the operation thereof can be readily understood. Referring part-icularly to Fig. 3, the wrapping operation on a roll r is just being completed. The carrier members 15 are held by engagement of the detent pin et2 with the Wheel 38. The

teeth on wheel 80 have just left. the Wheel 79 after a feed operation of the paper feed mechanism, and the cam groove 97 and cam roller 98 have coperated to cause the knifeto sever the wrappingpaper bands. /Also, substantially immediately after the knife has been lowered thecam teeth 106 have cooperated vvith the cam rollers 107 to cause discharge of paste from the receptacles 99 and 99 to the trailing ends of the paper bands which are to form the end vvrappings for the roll o" in place on rollers 16 and 17. In the positionsshovvn, therefore, vthe end Wrapping operation of the roll r has just been completed, and the roll is ready to be discharged from the rolls 16 and 17 into the heading mechanism. .Accordingly, as vvheel 80 continues to revolve from the position shown, particularly in F ig. 3, the cam tooth 51 will strike cam roller 50 o-nk cam lever 46, and the detent pin 42 will be Apulled down to release the wheel 38 and therebyA the members 15, and these members are` then driven to discharge the roll r forwardly from the rolls 16 and 17 and into the heading mechanism and to feed to the rolls 16 and`17 the next roll r2. During travel of the roll 'r2 toward the rolls 16 and.17 the teeth on wheel 80 are again approaching the gear wheel 79, and the teeth Will have been in engagement for a tinie before the roll r2 rcachesthe rolls 16 and 17, so that the wrapping paper feed mechanism will have been actuated a suficient length of time to carry paper forwardly over the roll 17 and into position to be engaged between the roll r2 and roll 17 when the roll r2 finally comes to rest on the rolls 16 and 17. The wrapping paper bands having had 'paste applied thereto will then of course stick to the roll r2, and the peripheral speed of the rolls 16 and 17 being adjusted to be substantially the same as lthe speed given the paper by the feed mechanism, the paper will be wound about the ends' of the roll r2, and as soon as enough paper has been fed the feed mechanism stops and the knife immediatelysevers the paper and paste is applied tothe ends of the severed bands, and these pasted ends'are then finally Wound against the roll r2. Of course, during the rotation of the roll r2 the folding members 36 and 37 are rotated, andthe over-hanging ends of the paper bands are folded together, and the paste applied to the bands by the mechanisms 99 and 99 becomes effective to secure the folded bands to prevent unwrapping thereof. To assist in guiding and holding the paper in place on the rolls during thev Wrapping operation, arms 108 and 108 extend from shaft 11 and pivot rollers 1709 and 109 between their ends which engage the ends of the rolls to Vbe wrapped,and due to their Weight .keep the wrapping paper snugly in place and preventunwrapping thereof. The rolls are also guided on their Way from the chute to the rollers 16' and 17 by arms 110 extending downwardly from the chute structure. The shaft 49 controlling 'the various cam mechanisms and the operation of the paper feed mechanism is driven by means of a sprocket chain 111 passing over the sprocket Wheel 112 on said shaft, and the sprocket wheel 113 on` the shaft 114. This shaft carries a gear 115 meshing With a driving pinion 116 on the shaft 117, which shaft carries the driving pulley 118. 4

I shall now describe the heading mechanism of the machine. The shaft 114, just referred to above, extends transversely across the front of the machine and is journaled in bearing standards 119, 119 and 120, and carries various mechanisms and cam mechanisms for controlling the operation of the heading mechanism. As best shown in Fig, 5, the supporting frame of the machine in front of the rollsy 16 and 17 'carries support bars 121, 121 for receiving the rolls after they leave the grappling rolls 117, and an incline 122 leadsfrom the roll 16 to the bars 121'. These bars support transverse bars 123 and 123 and 124,'which nally from movement during the heading o 1eration. At each side of this space into w ich the rolls are delivered to be headed heading mechanism is provided, the heading mechanisln on one side being exactly the same both as to construction and operation as the heading mechanism at the opposite side, and only one such heading mechanism need therefore be described. Referring to Figs. 4 and 6, a bearing standard 125 slidably supports a sleeve 126 terminating infa cir- `cular head 127 at its inner end, the 'sleeve being bored to slidably receive a rod 128 having at its `inner end a disk 129 provided wi th a center pin 130. Extending inwardly from the head 127'is an. annular blade 131 which coperates with an annular plate 132, this plate being supported at the inner ends of studs 133 extending slidably through the head 127, compression springs 134 encircling the studs rbetween the shearing plate and the head. Inwardly of the bearing standard 125 a standard 135 has the annular head or sleeve 136 carrying at its outer edge the annular shearing bladeor ring 137.

As will be explained morein detail later.l the paper from which the heading blanks are cut is fed downwardly between theannular plate 132 and the shearing ring 137, so that when the head 127 is moved inwardly thepaper will be clamped between the'plate 132 and the shearing ring 137 by force `o'f springs 134, and the blade 131 will then pass through the plate 132 and its edge will cooperate with the inner cutting edge of the ring 137 to cut a circular heading blank from the paper, which heading blank is received on the pin 130 and is then carried, upon further inward-movement of the rod 128,

lagainst the end of the roll by the head 129,

paste having continuously been applied to the paper. The operation of the shearing head 127 and the placing head 129 is controlled by levers 138 and 139 coperating with cams 140 and 141 respectively mounted on t-he shaft 114. The lever 138 is pivoted at an intermediate point 142 to the machine frame, and 'its inner end is pivoted to the outer `end of sleeve 126'at 143, while the outer end carries a cam block 144 which coperates withthe cam 140, this cam having the cam slot 140. Lever 139 is pivoted at an intermedia-te point to the machine frame at 145, its rear end being pivoted at 146 to the outer end of rod 128, and the outer end having a cam roller 147 coperating with the cam 141, which has the laterally extending cam ridge 141. In the normal position shown in Fig. 6, the cam mechanisms are in such position that the sleeves 126 and rods 128 are in their outer positions with the heads 129 resting against the inner face of the heads127. Referring to Figs.

vto have the blank .to receive the corresponding rod 128 anc'.

pressesl inwardly against the outer end of the sleeve 126, tending to move the sleeve and its head 127 inwardly. However, such inward movement is normally prevented by the engagement of cam block 144 with thc high part of the cam 140. As the shaft 114 is rotated the'levers 138 and 139 are also rotated about their pivots. Thecam blocks 144 first drop into cam grooves 1,40 to allow the springs 148 to move the heads 127 inwardly to cause the shearing of header blanks from the supply paper, and immediately thereafter the cam rollers 147 engage with the cam ridges 141', and the rods 128 are moved inwardly so that thesheared blanks, are carried by heads- 1294 against the folded ends yof the rolls fed into they heading field. This `position of the parts is shown in Figs. 4 and 7. v

Coming now to the paper feed mechanism for the headerv blanks, a table 150 is provided at each side of the machine adjacent the heading li'eld.. On each table a standard 151 carries a rod152 for mounting a supply paper roll 153. In front of this standard is a bearing bracket 154 carrying at its front upper and lower feed rolls 155 and 156 respectively. and at the outside of the top roll 155 carrying a paste applying roll '157, this paste roll dipping into a suitable paste containing pan 158. At the outside of the standard 151 bearing blocks 159 journal a guide roll 160. The paper passes from the roll,about the guide roller 160, then between the upper and ,lower rolls 155 and 156, and thence `downwardly between the annular plate 132 and shearing ring 137. The paste roll 157 engages the upper roll 155 to apply paste thereto, and this upper roll in turn applies the paste to the paper before it passesbetween the shearing edges heads cut therefrom. The feed and paste rolls are suitably driven by means of a chain -161 passing about a sprocket wheel 162 at the inner end of a shaft 163 journaled in the standard 135. This shaft at its front end carries a pinion 163 which meshes with a gear 164 mounted on shaft 114. At its rear end this shaft 163 also carries a gear 165 meshing with a gear 166 on theinner end of shaft 167 which is parallel with the shaft 163 and which carries feedrolls 168 and 169 between which and the outer face of standard 135 the pa er is passed after it leaves the shearing mec 1anism, the rolls by` their engagement with this paper serving to keep' the paper stretched across the shearing edges during the shearing operation. The paper feed mechanism should, of course, be operated intermittently and only at times when the heads 127 and 129 are in their outermost position. accordingly, clutch mechanism is provided for automatically cutting in the paper feed mechanisms during this time.

to each sleeve is the bifurcated ends 174 of a shaft lever 17 5, these levers being pivoted at an intermediate point to a cross bar 176 secured to the standards 135. By referring to Fig. 4, the left le'ver 175 has connected to its lower end a link 177 which pivots at its other end about the lower end of a supplemental lever 17 8 pivoted at an intermediate point to the cross bar 176 and carrying at its upper end a cam roller 179 for coperating with the cam disk 180 on shaft 114. A link 181 connects the upper end of the supplemental lever 178 with the lower end of the right lever 17 5, so that upon coperation of the cam roller175 with the cam ridge 180l both levers 175 will be swung tocarry their clutch heads 173 into frictional engagement with the clutch pockets 171 whereupon hubs 170 will be rotated and the paper feed` mechanisms for the heading blanks actuated. The paper having had paste applied thereto, the blanks carried inwardly by the heads 129 will be secured to the ends of the rolls and against the folds of the wrappers, and the wrapping operation is com leted. After such appllcation of the hea s the sleeves 126 and rods 128 are restored to their normal positions by engagement of the cams 140 and 141 with the levers 138 and 139.

As before stated, the rolls are held lin place on the bars 121 by the ridges 123 and 124, and-I therefore provide means for ejecting a roll from the machine after the paper heads have been applied to the ends thereof. As best shown in Figs. 5, 6 and 7, a shaft 182 is journaled in standards 135 and carries two ejecting arms 183. Between these arms this shaft also carries an arm 184 with which is connected a slotted link 185 receiving the shaft 114. 0n this link there is also a cam roller 186 adapted for engagement with a cam tooth 187 on the hub 188 mounted on shaft 114. During heading operation the ejecting arms 183 are dropped below the roll between the head applying mechanisms, and immediately after the heads have been applied lthereto the cam tooth 147 engages the cam roller 186 to move the link 185 inwardly to cause rotation of shaft 182 and to cause the ejector arms 183 to engage with' the roll and to force it out of the machine to the front ends of the supporting bars 121 where it can be conveniently removed.

after the wrapping operations have been all f.

carried out automatically.'
